Observadores derivativos e exponenciais numa coluna de destilação binária.
Keywords in Portuguese
Colunas de destilação
Abstract in Portuguese
No presente trabalho realiza-se um estudo do processo de destilação binária em colunas associado ao problema da estimação de seus estados dinâmicos. Se descrevem os principais modelos fenomenológicos de colunas de destilação binárias assim como as aproximações nos que foram construídos. Também se estuda o problema da estimação linear e não-linear para o caso específico dos observadores: filtro de Kalman Estendido. Se constróem dois tipos especiais de observadores para colunas de destilação binárias: Derviativos e Exponenciais tipo filtro Estendido de Kalman. Seu desempenho é avaliado e são feitas comparações dentre os dois. Finalmente, é apresentada a conclusão do trabalho, além de sugestões para trabalhos futuros.

Abstract in English
In this work it is performed a study about the process of binary distillation in columns associated to the problem of estimation of its dynamics states. The main phenomenological models of binary distillation columns are described, as weel as the approximations in the ones that were built. It i salso studied the problem of linear and non-linear estimation for the specific case of observers: Kalman filter and Extended Kalman filter. Two special types of observers for binary distillation columns are built: Derivatives and Exponential of the kind Extended Kalman filter. Its performance is evaluated and comparisons are made between the two observers. Finally, it is presented the conslusion of the work, besides suggestions for future works.
